AF/DF方式下自适应中继协作方式的研究与仿真

摘要

放大转发(Amplify Forward,AF)和译码转发(Decode Forward,DF)是中继协作通信技术中两种基本的中继协作方式.在研究两跳中继协作通信技术中AF和DF中继协作方式的基础上,针对基于门限的自适应中继协作方式,利用RN的位置信息提出了改进的自适应中继协作方式,并用蒙特卡洛方法对其仿真结果进行验证.结果表明所提出的改进自适应中继协作方式具有较好的协作性能.%AF and DF are two basic relay collaboration approaches in communication technology.AF and DF relay collaboration approaches in two-hop relay cooperative communication technology are researched on,and proposed an improved scheme that based on the threshold adaptive relay collaboration approach and the location information of the relay node,besides,the performance of the scheme was verified with Monte Carlo method.The result shows that the scheme achieved better cooperative performance.
